Hello guys,
When I upgraded my project from UE 5.3 to UE 5.4,
I am getting same error, and also have tried above maintained solution, that doesn’t fix the problem for me.
Disabled live coding in editor and restarted my computer. Also reinstalled VS and every abovementioned possible fix on the internet. Started working.

Editor and Game Target.cs files of old project may need
DefaultBuildSettings = BuildSettingsVersion.Latest;
IncludeOrderVersion = EngineIncludeOrderVersion.Latest;

I started to see this error when migrating from 5.3 to 5.4.2, and i added these lines on ProjectName.Target.cs AND ProjectNameEditor.Target.cs and solved the issue, thanks a lot!.
DefaultBuildSettings = BuildSettingsVersion.V5;
IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_4;

My environment:
Visual Studio Community 2022 17.10.3
Unreal Engine 5.1.1/Unreal Engine 5.3.2
JetBrains Rider 2024.1.4 RD-241.18034.76
Using Visual Studio 2022 14.38.33139 toolchain
Error reported during compilation：
10>Microsoft.MakeFile.Targets(44,5): Error MSB3073 : The command “D:\UE_5.3\Engine\Build\BatchFiles\Build.bat NetworkTeachingEditor Win64 Development -Project="C:\Users\My\Documents\Unreal Projects\NetworkTeaching\NetworkTeaching.uproject" -WaitMutex -FromMsBuild” exited with code 6.
I deleted the following files/folders, then right-clicked the .uproject file and clicked Generate Visual Studio project files. After recompiling, there was no such error. This is useful to me.
.idea
.vs
Binaries
DerivedDataCache
Intermediate
Saved
.vsconfig
NetworkTeaching.sln
This solution fixed it for me… i converted my project from 5.2 to 5.4, finally its working now again after 4 business day…
I’d like to supplement one more thing, I always get this problem when I compile the code while running Editor. Finally I solved this problem, I think this is the right way.
Editor Preferences → General - Live Coding → Uncheck
Enable Live Coding
This worked for me too. Thanks!
This is really heloful for me !
